is the first armoured dinosaur known to have lived in Antarctica,
though it should be pointed out that when Antarctopelta
Antarctica was not covered in snow and ice. Antarctopelta
kind of dinosaur called a nodosaur
which means that in life it would
have had a squat quadrupedal profile. The back and sides of
Antarctopelta would have been protected by a
covering of bony
armour called ostederms as well as possibly some spikes so that the
teeth of predatory dinosaurs could not get through. This was a
similar survival strategy as that used by the closely related
ankylosaurids, but as a nodosaur, Antarctopelta
would have lacked a
Antarctopelta likely shared its habitat with ornithopod dinosaurs like Trinisaura.
